Ponente: Santiago Montero-Mendieta Title: A genomic view on the diversification of neotropical frogs Abstract: The genus Oreobates is a clade of Neotropical frogs of which very little is known. More than half of the 24-named species have been described in the last ten years. They are distributed across a wide range of habitats and altitudes in South America. Unfortunately, some Oreobates species have been only found once. This is particularly a problem for traditional phylogeography and phylogenetics studies based on data from a few orthologous loci from multiple individuals. With the increasing usage of high throughput sequencing we are now able to sequence big amounts of orthologous loci, allowing the use of less individuals. In organisms with big genome sizes, such as amphibians, a common way to obtain a reduced representation of the genome is by transcriptome sequencing. Using a transcriptome-based exon capture approach, in my PhD thesis I will use thousands of orthologous genes to study evolution rates, demographic history and adaptation patterns on the frogs of the genus Oreobates. The results of this project will allow us to solve questions such as: “Is the evolution rate lower in the highland Oreobates species?”, “Is the genetic diversity larger in montane Oreobates species?” or “Are there any genes related to adaptation to dry forest in Oreobates?”.
